Transcend doesn't show my laptop model number in it's compatibility search list (for memory modules). Please help.

Laptop is Sony VAIO VPCEB34EN.

Thanks,

The cheaper modules rated 1333 MHz would be the better choice due to their low price.

Assuming the modules are compatible with the laptop (as per the above list), the only compatibility issue that may occur is when using two (or more) of the same modules at the same time, regardless of memory frequency.

Each module has unique characteristics, no two modules are exactly alike, even for modules with the same part number. In order for two or more modules to work together, the modules characteristics have to be identical or close enough to each other to allow compatible stable operation.

So when using several single modules at the same time, it might take several attempts using different modules (with the same part number) to find the...
Welcome back!

The following Transcend/JetRAM modules should be compatible with the VAIO VPCEB34EN laptop.

DDR3-1066 modules -

TS128MSK64V1U <- 1 GB @ 1.50 V

TS256MSK64V1U <- 2 GB @ 1.50 V

TS256MSK64V1N <- 2 GB @ 1.50 V

TS512MSK64V1N <- 4 GB @ 1.50 V



DDR3-1333 modules, will (or should) run at 1066 automatically -

TS256MSK64W3N <- 2 GB @ 1.35 V

TS512MSK64W3N <- 4 GB @ 1.35 V

TS128MSK64V3U <- 1 GB @ 1.50 V

TS256MSK64V3U <- 2 GB @ 1.50 V

TS256MSK64V3N <- 2 GB @ 1.50 V

TS512MSK64V3N <- 4 GB @ 1.50 V

TS256MSK64W3N <- 2 GB @ 1.35 V

Thanks!

Good to see you again. Glad you came to answer my question! :)

I found that my laptop uses low density sticks. Are those part numbers all low-densities?

One more thing. If a 1333 MHz (that has slower CAS latency like 9 or 10 or 11) is installed in my laptop, the speed will get down clocked to 1066 MHz,
what happens to the CL ?

The currently installed modules are at 1066 MHz cl7.
 


Yes. All of the listed modules use low(er) density memory chips.



The CAS Latency will (or should) be adjusted to lower number (faster memory response) automatically. The actual value of CAS Latency will depend on the memory chips used and on the modules SPD data.

Why I'm asking about the CL is that 1333 MHz C9 (low dense chips) are available cheaper than the 1066 MHz C7 (low dense chips too).

But it is not much of cost difference per module (say the difference is 15% for one module).

On getting 2 modules, the difference is the cost of a 32 GB pen drive.

Is it worth getting those cheap 1333 MHz (will this have compatibility probs?) , or bit costlier 1066 MHz and be problem-free?
